Visible crew/equipment: After Arthur drinks from the Grail and goes to visit Gwinevere at the convent and she gives him the sword back, he paces around her chamber- you can clearly see the film crew reflected in his armor.

Other: When Uther takes the baby from Igrayne and gives it to Merlin, Igrayne's screaming and whimpering is not consistent with her mouth movements.

Other: When Arthur and all his knights assemble on hilltop at night and Merlin tells them all not to forget where the Round Table started, you can see the crew's spotlights reflected on the back of some of the knights' armour.

Continuity: After the final battle Mordred thrusts a spear through his father Arthur's chest. It goes totally through him but if only the very tip has blood on it. Later on in the scene it's entirely bloody.

Continuity: Perceval throws Excalibur into the lake and we see that it's full of blood as it flies through the air, but as the "Lady of the Lake" catches it there's no blood on it. Then as she lowers it into the water there's blood on it again.

Continuity: Uther wants Merlin to get Igrayne for him to sleep with and they both climb to the top of a hill so that Merlin can cast a spell on her. Merlin says, "Annal Nathrach" with his scepter held high in the air but in the next shot the scepter is at eye level.

Continuity: At the siege of Leondegrance's castle, Arthur gives Uryens Excalibur and asks him to knight him with it. Arthur has been out of the water for a few minutes but as he is being knighted his hair is dripping wet again and a large area of blood appears on his neck.

Continuity: In a long shot, Mordred brings Perceval to Morgana and she says as she holds him, "My lovely, clever boy". The next shot is a close-up and the blankets covering her throne are entirely different.

Continuity: King Arthur asks Merlin where evil is in his kingdom and he replies, "Always where you never expect it, always". In the next shot Morgana walks back to her seat at the table as Gawain blurts out, "I know where" but then two shots later we see her back at the wall where she was speaking to Merlin.

Continuity: As King Arthur addresses the Knights of the Round Table he says, "Only the Grail can restore leaf and flower" and Perceval and the other nights are facing him. In the next shot Perceval and the knight to the left of him are facing forward with only their heads turned towards Arthur.

Continuity: Mordred brings Perceval to his mother Morgana and we see the metal pendants hanging from her crown are almost motionless. In the next close-up shot of her holding Mordred the pendants are all moving.

Continuity: Igrayne Says, "My lord" as Uther takes her into his arms. At first she holds him with her right hand around his waist but in the next shot her right hand is on his arm.

Continuity: As Morgana and Merlin speak, the position of the vial that she's wearing changes between shots. In the shots where we see Merlin's face a gold spec (many are included as decorations in the veil) is next to her cheek. In the shots where we see Morgana's face the gold spec moves and is next to her right temple.

Continuity: King Arthur's second horseman carries three extra jousting sticks as they ride to the far end of the field preparing for the joust. After the first charge Lancelot says, "You joust well, Sir, I offer you another lance" and King Arthur rides back to his second horseman who now only has one jousting stick.

Continuity: Uther thrusts Excalibur into the side of the stone. In the next shot many years later, Excalibur is stuck into the top part of the stone.

Continuity: After the fight Lancelot lies dying and King Arthur says to Merlin, "Bring him back, whenever the cost". Guinevere lifts Lancelot's left hand and kisses it but in the next shot both of her hands are on his wound.

Continuity: Arthur instructs Perceval to, "Take Excalibur, find a pool of calm water, throw the sword into it". No one ever removed the spear that Mordred thrust through his chest but now as Arthur dies it's gone.

Continuity: As Guinevere drinks from the chalice the priest gives them, she lifts her veil with the fingers of her left hand in a horizontal position. In the next shot her fingers are pointing upward.

Audio problem: As he chases Merlin into the wilderness, Uther takes Excalibur and trusts it into the stone. The battle didn't take place there, but if you look at the mud around the stone there are many footprints from the crew members' feet.

Continuity: King Arthur extends Excalibur out to Lancelot who grabs it with both hands. At first Lancelot's right hand is at the tip of Excalibur but in the next shot his hand touches the sword about four inches away from the tip.
